H04.0: Dacryoadenitis

The lacrimal gland is above the outer corner of the eye. The lacrimal gland produces the tear fluid for the eye. The film of fluid (tear film) on the eye, together with the conjunctiva and the eyelids, protects the eye from external influences.

When the lacrimal gland gets inflamed, the upper eyelid may swell up. The swelling can persist for a long time. The eyelid may also turn red and be painful if you press on it.
